As Busch's crew chief Steve Addington and spotter Jeff Dickerson told their driver on the radio at the end of Saturday night's Lifelock.com 400 NASCAR Sprint Cup race at Chicagoland Speedway, a race, like a baseball game, truly isn't over till it's over -- even if the driver thinks it is.

On a restart with two laps remaining in the 267-lap event at the 1.5 mile speedway, Busch roared to the outside of leader Jimmie Johnson and cleared the No. 48 Chevrolet through Turns 3 and 4. On the final lap, Johnson made a run up to the bumper of Busch's No. 18 Joe Gibbs racing Toyota but could get no closer, as Busch held off the Lowe's Chevy by .159 seconds at the finish.

For Busch, who had radioed, "Race over," after Johnson passed him for the lead under green on Lap 251, the victory was the seventh of the season and the 11th of Busch's Cup career. It also marked the first time since Tim and Fonty Flock strung together four wins in 1955 that brothers have accounted for four straight victories.

Kyle won at Infineon Raceway on June 22 to start the streak, with brother Kurt Busch's triumph at New Hampshire preceding Kyle's victories at Daytona and Chicagoland.
